24 Claims.

This invention relates to improvements in wrapping machines particularly adapted, though not necessarily limited in its use, for wrapping bars or sticks of candy, and one of the objects of the invention is to provide an improved machine of this character which will be of a comparatively simple and compact construction and which will be effective and eflicient in operation.

A further object is to provide an improved ar- 1 rangement in the folds of the wrapper about the article.

To the-attainment of these ends and the accomplishment of other new and useful objects as will appear, the invention consists in the features of novelty in substantially the construction, combination and arrangement of the several parts hereinafter more fully described and claimed and shown the accompanying drawings illustrating this invention and in. which Figure 1 is a front elevation of one end of the machine. Figure'2 is elevation taken from the side of the machine opposite to the side from which Figure 1 is taken, and with thecover for the casing removed, showing a portion of the operating mechanism.

Figure 3 is a view taken on line 3-3, Figure 1, on an enlarged scale, with parts omitted and with parts broken away.

Figure, 4 is a vertical, longitudinal, sectional view of the machine, as taken on line 4-4, Figure 3.

Figure 5, is a ertical sectional view similar to Figure 4,on.an enlarged scale, with parts omitted and showing. others of the parts in a diiferent position fromthat shown in Figure 4. .Figure 6 isaview'similar to Figure 5, showing the parts in ,another' position. Figure T is a horizontal sectional view taken on line l-I, Figure. 6, with parts omitted.

Figures 8, 9,10, 1I and 12 are detail perspective views showing the different steps in the operation of folding the wrapper about the article. ,Figure 13 is a detail-sectional view showing the manner of advancing the article just after it has beenwrapped. a. -M- I Referring moreparticularly to the drawings the numeral 20 designates a supporting structure which is'preferablyin' the'form of a housing pro- 'videdwitha removable closure for housing certain ofthe"'operatingmechanisms to be hereinafter described. 'lhis housingfll serves as a supportfor a hopper-or container 2| which is arrarigecl adjacent the closed side of the housing for holding the wrappers 22, and which wrappers-are ejectedlthrough the bottom thereof by meansof one or more rollers '23 having a friction surface-24 preferably in the form of rubber or the like i to engage 'the bottom wrapper and remove the same from 'the'hoppen A supporting pin or element 25 may be provided for supporting the rear ends of the wrappers while in the container.

The wrappers are delivered into a guideway 26 and are advanced by means of co-operating rollers 21-23 through the guideway to be positioned, 5

in a manner to be set forth, so as to be contacted by the article which is to be wrapped. Certain of the rollers 23-21 are positively driven, while the rollers 23 may be spring pressed to co-operate with the respective rollers 21 for gripping 10 and advancing the wrappers.

The wrapper feeding rollers are preferably supported by a frame 29 which may be removably secured in position preferably by means of fastening screws 30, and'the pin or element 25 may be 15 adapted for adjustment and is held in position by means of a fastening screw 3|. It will therefore be manifest that the feeding rollers together with the guide 26 which is also mounted upon the support 29, may be readily removed when desired.

Supported below and spaced for a considerable distance from thebottom of the hopper or container 2|, are guide rods or bars 32-33 held in position by means of suitable brackets or bearings 34, and these rods or guides 32-33 consti- 25 tute supports and guides for a reciprocable carriage 35, reciprocation being imparted to the carriage by means of a lever 33' (see particularly Figure 1) pivotally mounted intermediate its ends as at 31 and provided with laterally projecting portions 38 (see-also Figures 3 and 4) at the top thereof, and to which portions one end of links 39 are pivotally connected as at 40. The other end of the links are respectively connected 35 as at 4| to the carriage 35. To the other end of the lever 36 is connected one end of a linkv 42, and the other end of the link 42 is connected as at 43 to a crank disc 44 secured to a shaft 45, so that when the crank 44 is rotated the carriage 35 40 will be reciprocated. The carriage 35 and the bars or rods 32-33 are of such a length with respect to each other so as to permit of a free reciprocation of the carriage.

Motion is imparted to the shaft 45 from a motor 46 (see particularly Figure 2) mounted. upon a suitable bracket 41 secured to the casing or support 20. To the shaft 43 of the motor is secured a pulley 49 over which an endless belt 5|! passes, and the belt also passes over a pulley 5|, which latter has secured thereto for rotation therewith a sprocket wheel 52, over which a sprocket chain 53 passes, and this sprocket chain also passes over a sprocket wheel 54 which has secured to it and for rotation therewith a gear wheel 55 which 55 meshes with an idle gear 56, and this gear in turn meshes with a gear 51 that is secured to the shaft 45.

-A clutch member 53 is provided between the motor 43 and-the gear 55 for controlling the operation ofthe gear, and this clutchmember is but the springs permit controlled by means of a control lever 68, conveniently positioned for the operator.

As the motor-is continuously rotating, it will be manifest that by the operation of the lever 58, the clutch 58 will be controlled, and therefore the reciprocation of the carriage 86 will be corr spondingly controlled.

Extending across the body portion of the carriage 35 is a support 68 preferably formed by means of spaced members 6|, and this support is provided with an upwardly curved portion 62 terminating in a horizontal portion 66, which latter extends forwardly to the point at which the wrapper and articles are delivered thereonto. Carried by the portion 63 of this support and in advance of the upwardly curved portion 62, are pivotally mounted members 66 preferably provided with projections 65 to be engaged by leaf springs 66 which tend normally to project the edges 61 of the members 66 above the top of the portion 63 of the support, for a purpose to be described.

Carried also by the portion 66 of the support are fingers 68 pivotally mounted as at 68 and which also project above the top of the portion 63 of the support. The respective fingers 68 and members 64 may be mounted upon the same pivot and any number of these members and fingers may be provided. Springs 18 are also provided so' as to yieldingly hold the fingers 68 i in the path of movement of the advancing articles, in a manner to be later described.

Arranged above the support 68-62-48 is a guide 1| which is also preferably formed of spaced members as shown more clearly in Figure 3, and pivotally mounted at the forward end of the guide 1| are retaining members 12, any number of which may be'provided. Springs 18 individual to these members '|2' are provided which tend normally to hold a portion of the members 12 in the path of advancing movement of the article, the members 12 to yield so that the articles may pass thereunder and then return the members 12 to the position shown in Figure 5, to hold the article against retrograde movement upon the portion 66 of the support.

Supported also by the guide 1| and adjacent the upwardly curved portion 62 of the support 68 are pivotally mounted fingers 16 controlled by springs 15 and which springs tend normally to hold the fingers 18 in the path of the advancing movement of the articles.

The guide 1| is preferably removably held in position by means of lugs 16 (see particularly Figures, 1, 3, 4, 5 and 6) which are adapted to enter open seats 11 provided in supports 18 at one end of the guides 1|. At the other end of the guide 1| lugs 18 are provided which engage behind a projection 88 on a support 8|, and latch members 82 pivotally mounted as at 88 are provided on the support 8| so as to co-operate with the projection 88 and engage behind the lugs 18.

Thus it will be seen. that by swinging the latch 82 about its pivot 83 the guide 1| with the supporting parts, will be freely removable from the machine.

The guide 1| is so arranged as to form a space above the portion 68 of the support 68 which is only slightly greater than the cross sectional diameter of the article so that when the wrapperis partially applied to the article, in a manner to be set forth, and to move upon the portion 63 of the support 68, the guide 1| will co-operate with the support 68 to partially fold the wrapper and hold the wrapper and article in proper position with respect to each other during the advancement and wrapping of the article.

Arranged beneath the guides 26 are upwardly opening mil tentially U shaped members 84 constituting ctr. for receiving the wrappers 22 i from the guides 26 and these members 84 are so arranged that when a'wrapper is deposited thereinto (see particularly Figures 4 and 5) the wrappers will extend across the space between the portion 68 of the support 68 and the for- 10 ward edge of the guide 1| to be contacted by the article 85 when the latter is delivered on to the portion 63 of the support, thereby carrying with it the wrapper. These members 36 (see particularly Figures 3 and 7) are mounted to swing 15 about upright pivots 86, such as hinges to be moved out of the way of the operation of the other partsto be described. The hinges 84 are preferably of the spring type. so as to return the members 86 during a portion of the cycle of operation of the machine. These members are so arranged that when the article 85 contacts the wrapper it will do so at substantially its central point, as shown m0re clearly in Figure 4.

The articles to be wrapped are fed into the machine in any suitable manner, preferably by means of an endless conveyor 86 having pockets 81 thereon and which conveyor passes over a sprocket wheel 88 mounted upon a shaft 68. Two of the endless conveyors 86 with pockets 81 secured thereto, are preferably provided, and arranged to operate between the members 86 and the sprocket wheels 88 is a plunger 86 (see particularly Figures 3 and 4) which is pivotally mounted as at 8|, and this plunger is provided u with a head 82 which preferably projects laterally beyond the plunger so as to engage a substantial portion of the article 86. The forward end of the plunger moves over a support 88 (see Figure 4) upon which the articles 86 are deposited from the conveyor by inverting the pockets 81 as the conveyor travels. As soon as an article is deposited upon the support 86, and after one of the wrappers 22-has been positioned as shown in Figure 4, the plunger 86 is rooted about its pivot 8| so as to engage the article upon the support 88 and advanced to move the article into contact with the wrapper 22 in the pockets 86. A further movement of the plunger will cause the wrapper to be withdrawn from the pockets at by the advancing article and both will be moved into the space between the portion 68 of the support 68 and the guide 1|. The article with the wrapper will then be-moved forwardly upon the support 68 until both have assumed a position behind the retaining members 12 to be retained in this. position while the plunger 88 is retracted to permit another article tobe deposited upon the support .86. .After the article and the wrapper have passed beyond the retaining member 12'it will engage the fingers 68 and both will be held in position until the article and wrapper are advanced, in a manner to be described. The retaining members 12 (see particularly Figures 4 and 5) also serve as a means for partially folding the wrapper about the 65 article.

Motion isimparted to the conveyors 86 intermittently by means of a pawl 84 (see particularly Figure 2) which is mounted upon an oscillatable arm 85 and which pawl engages a ratchet wheel 86. secured to the shaft 88. A rod 81. is pivotally connected as at 88 to the arm 88 and is. preferably provided with an eccentric strap 88' encompassing an eccentric I88, and which eccentric is connected with a crank m, to which latter is ment of the carriage 40- to the shaft SI, so that as the cam I04 is rotated an oscillatory movement will be imparted to the shaft 9| by reason of the roller I05 on the arm I06 traveling in the cam groove of the cam I04.

As a means for directing the wrapper into the pockets 84 as it is delivered from the'guides 26,

members I01 (see. particularly Figures 5 and 6) may be pivotally mounted as at I08, and a portion of these members are arranged normally in the path of movement of the advancing articles and serve as a means for assisting and holding the articles in position, but are adapted to be swung about their pivots by the article and by engagement therewith of theends 92 of the plunger 90.

Mounted upon the carriage 35 (see particularly Figures 4, 5 and 6), preferably by means of pivots I09, is a frame IIO which carries a plurality of upwardly projecting fingers I and which fingers are adapted to be projected'through slots II2 between the members constituting the support (see also Figure 7). A spring H3 is provided which tends normally to depress the member III! and thereby withdraw or lower the fingers III below the surface of the support 53 so as not to interfere with the advancing movement ofthe article 85 upon the support. The fingers III and the supporting frame, however, are mounted to reciprocate with the carriage 35 and during a portion of the reciprocating movethe spring II3 serves to lower the frame about its pivot and consequently the fingers III, but during the movement of the carriage during another portion of the cycle of operation the frame H0 is elevated so as to pro* ject the fingers II3 above the support 63 to engage behind the articles 85 and advance them along the support 63. This raising movement of the frame 0 and fingers III may be accomplished in any desired or suitable manner, preferably by means of a track II4 (see particularly Figures 3 to 6) supported by means of arms I I5 pivotally mounted as at H6, and which arms are pivotally connected to the track as at II1.

A stop H8 is provided for limiting the lowering movement of the track.

' The pivot of one of the arms II5 is formed by a rock shaft (see also Figure 2) which extends into the housing formed by the support 20 and to the shaft is connected an arm III), which latvalong the support 63 by the article approaches the downwardly curved ter is pivotally connected as at I20 to a member I2I having a bifurcation I22 which stands astride of the shaft 45. Connected to the member I2I ,is' a roller I23 which travels in a cam groove I24 of the cam member I04 so that as the cam member rotates, the shaft I It will be rocked to raise and lower the track I I4 at predetermined times ,in the cycle of operationof the machine. It will therefore be manifest that when the carriage 35 is moved in one direction and when the track H4 is raised, the member IIO will be raised to project the fingers I I I above the support 63 to engage behind the article and, as the carriage moves in the opposite direction and while the track H4 is raised the article will be moved the fingers III, and as and tends normally to raise the same so as to withdrawthe fingers I21 portion 02 of the support 08, the track II4 will be lowered so as to permit the spring I I3 to swing the frame IIO about its pivot and thereby lower or retract the fingers III.

Carried also by the carriage 35 larly Figures 4, 5 and 6) is another member I25 which is pivotally mounted as at I25. This member I25 is arranged'above, the guide H and the support 63 and is provided with depending fingers I21, which fingers are adapted to be pro- 10 jected through the slots or spaces in the guide 1I formed by the members constituting the guide.

A spring I28 operates upon the member I25" from the slots.

Slidably mounted in suitable guides I23 (see particularly Figures 2, 5 and 6) is a slide I30 having a projecting arm I3I of a substantial length. Carried by the member I25 is a roller I32 which I0 is disposed beneath and is adapted tobe acted upon by the lower face of the arm I3I so that when the slide I30 is raised, the member I25 will also be raised under the influence of the spring I28, but when the slide I30 together with the arm I3I is depressed, the face of the arm I3I willengage the roller I32 and will depress the member I25 against the stress of the spring I28 to cause the fingers I21 to pass through the slots in the guide H to engage to the rear of the article be- 30 hind which the fingers III engage, and both of these sets of fingers serve to advance the article along the support 63.

Any suitable means may be provided for reciprocating the slide I30 (see particularlyFigure 2), 85 but a simple and'emcient means embodies aim; or projection I33 connected to the slide I30, and this lug I33 projects through a suitable slot in the wall of the housing or support 20. Connected to the lug is a link I34 otally connected as at I35, to an arm I35, the latter being pivotally supported intermediate its ends as at I31. The link I34 is pivotally connected as at I38 to one end of a link I39, which latter is in turn pivotally connected to the mem- 45- 1 of them are moved on to the support I53 beneath the guide H to a position behind the retaining member 12 and in advance of the fingers 68, and the parts'have assumed the position shown in Figure 5, the track II4 will be lowered and the member IIO wil be lowered, while the member I25 will be elevated, due to the fact that the slide 30 is elevated. This will occur just before the carriage 35 reaches thellmit of its forward movement. At this time and upon a further movement of the parts shown in Figure 5 to the position shown in Figure 6, the track II4 will be elevated and the slide I30 will be lowered so as to cause the respective members H0 and I25 to 70 assume the positions shown in Figure 6, so that the. fingers III will be in the rear of one of the wrapped articles, while the fingers I21 will be in the rear of a partially wrapped article. The

carriage 35 will then be moved to the left from 75 (see particu- 5 and this link is also piv- 40 plunger 55 into, engagement with the wrapper 22 and as both the position shown in Figure 6. so that the fingers I I I will advance the completely wrapped article 65 while the fingers I21 will advance a partially wrapped article 65 along the support 63 and until the foremost article is moved by the fingers III to a positionto be forced down the curved portion 62 of the support 60. while the wrapped article will be arrested in its forward movement by the forward set of fingers 66, and the partially wrapped article will remain in this position until the fingers III are again raised to pass behind the partially wrapped article. During this. movement of the fingers III the extremities thereof will engage the portion of the wrapper 22 the article and will force this portion of the wrapper against the article so that upon advancement of the article then being acted upon, the wrapper will be sealed against the article.

This operation continues as the articles are being fed into the machine and wrapped.

It will therefore be manifest that the fingers I21 serve as a means for folding down a portion of the wrapper against the article while the fingers III serve as a means for folding another unwrapped portion of the wrapper against the article and over the folded down by the fingers I21. Both sets of fingers, however, serve a further function; of intermittently advancing the article along the support 63.

Before the articles fingers I21, and as the article is being positioned by the head 92 of the plunger 90 (see particularly Figures 5 and 6) the article first contacts with the wrapper 22 and the ject the plungers I43 towards each other and towards the extremities of the laterally projecting portions I42 so as to engage the end of the article and the wrapper to assist in folding the wrapper, and at the same time are resiliently yielding so as not to injure the article or the wrapper.

These members I40 are provided with arms I46 to which one end of an adjustable link I 41 is which has not been folded against portion which has been.

arrive at a position to be is positioned tobe engaged by the track II4, so that when the track H4 is raised, the shaft III will be rocked in a direction to force the ends I42 of the folding members I40 toward each other. against the wrapper and over the end of the 6 article, but :when the track H4 is lowered the folding members I 40 will move away from each other and out of engagement with the ends of the article and the wrapper to permit an advancement of the partially folded article and the 10 further folding of the wrapper. Springs I55 (see I particularly Figure 3) may be provided which are anchored as at I56 by one end to the arm I5l and are anchored at their other ends as at I" and assist in and tend normally to return or 16 move the folding members into an inactive position.

As the articles (see particularly Figures 3, 4 and 6) have been completely wrapped and have been moved to the position shown in Figure 6 Just before the fingers III are retracted, the forward retaining members 64 will be depressed by the article passing thereover and the completely wrapped article will move to a position so as to be engaged by fingers and forced down the curved portion 62 of the support on to the portion 60. v'Io that end there is provided a shaft I58 which is provided with an arm I56 having a laterally projecting pin I60 that extends into a slotted member or hearing IH 35, and to the shaft I58 fingers I62 are secured, and these fingers are arranged preferably adjacent the fingers l4 and are. disposed; when the shaft I58 is rocked in the proper direction, to

engage over the top of the article, and when the fingers are moved in the opposite direction to depress the same, will force the article down the curved portion 62 of the support 60, as shown more clearly in Figure 4, to cause the'article to be partially turned so that the folded portion of the wrapper will contact with the portion 62 of the support. The fingers I4 co-operate with the fingers I62 (see particularly Figure 4) to effect this movement.

The wrapped articles will be advanced along the support by reason of their contact with each other and through the intermediary of the fingers I62 forcing an article down the portion 62 of the suppo As the carriage 35 moves from the full line position shown in Figure 6, to the dotted line position, this movement of the fingers or memrocked to elevate the fingers I62. 55

The wrappers are fed from the container and into the guides 26 by the roller 23, and this roller 23 is mounted upon a shaft I 63 (see particul'arly Figures 2 and 4) which is positively driven by means of a sprocket wheel I64 secured 50 to the shaft and over which sprocket wheel a sprocket chain I65 passes. The sprocket chain also passes over a sprocket wheel on the crank shaft I 0I and also over a sprocket wheel I66.

I61 may be provided, 65 to the shaft L68 of which issecured a gear wheel I69, and this gear wheel meshes with a gear wheel I10 secured to the shaft III to which the sprocket wheel I66 is connected, for the purpose of adjusting or positioning the parts of the 70 mechanism by hand.

As the wrappers 22 are fed to be engaged by the article the plunger 60 and before the are delivered into the space into the pockets 84 being advanced by wrapper and article between the supcarried by the carriage port 83 and guide 1| orglue is ,applied to portions of the wrapper so as to seal the same around the article when the wrapper is comtop of the pot.

A rock shaft I11 is journaled in suitable bearings I18 and carried by the rock shaft are arms I19 and carried by the arms is another shaft I88 extending across the'space the'rebetween. A

plurality of rollers I8 I are secured to the shaft I 88,

and either one or both of the arms I19 is provided with a cam shaped portion or projection I82.

Secured to the shaft I83 of the roller I16 is a crank arm I84 carrying a roller I85, and one of these crank arms and rollers I84-l85 may be-provided for each of the arms I19. 1

A spring I86 tends normally to move the'arms I19 in a direction to cause the rollers I8I to engage the periphery of the roller I16, and when the wrappers are being fed into the pockets '84, the paste applying rollers I8I will assume the position shown in Figures 4 and 6. During a proper time in the cycle of operationof the machine and when the shaft I84 will be rotated, causing the roller I85 to swing the arms I19 and the rollers I8I about the pivots I11 against the stress of the spring I85, so as to cause the rollers I8I to contact with the lower portion of one edge of the wrapper at shaft IOI.

spaced intervals as indicated by the reference character I81 in Figure 11 of the drawings. The paste will be applied to the rollers I8I by the roller I15 and as soon as the roller I85 on the arm I84 passes out of contact with the high portion of the cam or projecting surface I82, the 'spring I86 will return the arms I19 and roller I8I to the position shown in Figure 6. The shaft I83 is rotated (see particularly Figure 2) by means of a sprocket wheel I88,= over which a sprocket chain I89 passes, and this sprocket chain I89 also passes over a sprocket wheel on the crank An idle sprocket wheel I98 may be provided, if desired, forengagementwith the sprocket chain I89 for holding the latter in position.

Thus it will be manifest that at a predetermined time in the cycle of operation of the machine, paste will be applied'to the wrapper and the rollers I8I will bemoved'into and out of engagement with the paste supplying roller I18 and also with the wrappers. I I

The wrapper isvapplied around the article by first folding the ends of the wrapper towards each other, then folding the intermediate portion of the folded ends around the article, after which the wrapper is then made to encompass the body of the article and sealed during the advancement of the article in the machine.

Referring to Figures 8 to 12- ofthe drawings, it will be seen that Figure 8 represents the'blank or wrapper when it is fed into thepockets 84 and with the article 85 in the'position' which it will assume with respect to the wrapper when it is advanced by the plunger 90, and with the paste I81 applied'at separated portions thereof. When the article is advanced into the space hea,o17,s14 y I wrapper will be in ,a position (see particul'a ly to stand upper and lower'walls fold-the endsof the I83 is rotated the arm the'ends of the article and the ends Figure '1) to be operated upon by'the folding members I42 whlchwill fold the ends e the wrapper over the ends of 'thearticle as'at I 9I, and between the partially folded wrapper'uflt 1 will be noted that the-ends of the folding mem- 'rs ll2aresubstantiallyushapein'crosssection, with the bottom of the U formation substantially upright sothat whenjthey are moved astride of the'ends of the article, the 15 perdown on the ends of the article and the ends of the portion I95 of the wrapper.v "At Y the same time'therewill be produced the folds I e: f I upon the portion I94-of the wrapper, thereby engo compassing the ends of the article 85 and between the edges I95, as shown more clearly in; Figure 10. As the folding members I48 are moved towards each other, they will engage and swing the pockets 84'about their pivotsflfias shown 25 in Figure 7. During the time that thefoldin'g members are operating upon the wrapper, ;the plunger 98 isadvancing the article alongfthe support 63, and as the article and partially folded wrapper passes beyond the end of the retaining 30 member 12, the spring 13 of the retaining member will force the latter downwardly into engagement with the upper folded edge of the wrapper'to partially fold the same, I 111i" The partially wrapped article will then 35 I a position behindthe retaining member 12 and in front of the fingers 58 so as to hold the article and wrapper while the plunger is being retracted. 1 I By this time in the operation ofthe'machin, 40

the carriage 85 will have been advanced tofthe position shown in"dotted lines infig'ure '6, '-and as the Slide I3! is in'its lowermost'positionit through the medium-of the roller I32, force the member I25 downwardly against the stress of-the 45 spring I28 and behindthe article which hasbeen partially wrapped so as to complete-the folding of'the upper edged the wrapper-which has been partially folded b'y the'retaining' members 12-5- The carriage 35 then moved in the opposite o direction carrying with it the member l25 and fingers I21,and these fingers will then 7 ove partially' wrappedarticle past the fingers "68', M
